To all wkmm't mag concern:

Be it known that I, Knmzern l3. STUART, .a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a. new and usefulVehicle-Buffer, of which the following is a specification.

My invention relates to buffers for railway vehicles forabsorbing shocks bet-ween cars'or vehiclesof a train. and for like purposes.

For an illustration of one of the forms my invention may take, reference is to be had to the accompanying drawings, in which:

' Figure l is a side elevational view of a car or vehicle haying my improvedbufi'er thereon. Fig. 2 is a top plan view of the' same. Fig. 3 is aside elevational view of :part of a car with the buffer construction shown in longitudinal section. Fig. 4 is a side elevational' view of one end of a vehicle, the buffer beingshown in section.

Upon the running' rails R R roll the wheels w of the car or vehicle, these wheels having journalsJ. between which" and the vehicle or car frame'C, here shown as-u. rolled channel section, intervene the springs S. The body o f'the car B is carried by the car frame C.

A leaf spring S extends across the end of i the frame Q and is supported thereon at its P carried by ends. Upon the Iifliring S,.substantially in the axis of the car, is a butler comprising the parts 13 and.B the former dispose in front ofand the latter back of the spring.

8, the parts B and B being secured together by bolts 13.

The members B 'carry coupling pins P and P and a link L for coupling-two cars together. In Fig. 2 the link at the front (left) end of the car is thrown over a pin a spring S to prevent the link from sw nging about. At the rear end the car is shown coupled to another car.

The buffer member B has an inwardly extending portion adapted to enter a recess in the car frame CL And with this aperture or recess in the can frame C registers the opening in fthe hollow member F Within the pocket so formed are disposed blocks F The leaf springs S carrying the buffers are intended to absorb the shocks of jolting between cars in ordinary runnin while the felt blocks are intended to abso the more severe shocks of collision, as where two cars. are brought together in coupling, the two forming a very simple and efficient bufl'er capable of absorbing the maximum amount of enemy that a car can have under conditions of trafiic. y

This application is a division from my application Serial No. 581208, filed Septemher 9, 1910.

What- I claim is 1. The combination with a car frame, of

a spring extendin across the end of said. herefrom, means securing t'rnme and spaced I said spring to said. frame at the-sides of saidvframe, a member having a pocket car ried by said frame. shock absorbing material in said pocket, and a butler block carried by.

said spring adapted to impinge upon said shock absorbing material;

2. The combination with a car frame, of a spring supported atits ends upon theend of said frame and extending across {the same and spaced therefrom, a butler block carried; by said spring, a member havinga pocket rigidly secured to said frame, shock absorbing material in said pocket, and an ex.- tension on said buiier block adapted to im-v pinge upon said shock absorbing material.

The combiimtionwith a car frame,' of a spring extending across said frame and supported at its ends at the sides of said frame, a member having a pocket, shock absorbing material in said pocket, said frame having an aperture registering with said pocket, and a butler block carried by said spring and adapted to impinge upon said shock absorbing material.

4. The combination with a car frame, of a. spring carried by said frame and extending across the end thereof, a member having a pocket carried by said frame. shock absorbing material in said pocket. a divided bufi'er embracing said spring and having an extension adapted to impinge upon said shock absorbing material;

pocket, :1 buffer block carried 10 said'spring 'imr said buffer block.
